I'm looking to create a multisite for an exercise franchise. As it's a franchise, most of the description will be the same apart from the location information. For some of the content I will use a canonical link. But what is the best way to deal with Title Tags and other content on the page with regards to SEO. For example if each site has a title tag of "Exercise classes in xxxxxxx" is it enough just to change the name of the location? And if the first paragraph of content has the same introduction but with location specific information, will this be detrimental for SEO? Thanks for your help - this will be the first Multisite that I have built so any advice is much appreciated.
